Easily board mounted
Requires no lead bending
No additional heat sinks required
Pin compatible with industry-standard, 14-pin laser
module
Highly efficient DFB-MQW laser structure allows
for lower threshold and drive currents, and reduced
power consumption
The low-profile D371-Type Laser Module is ideally suited for
short- and long-haul SONET and other high-speed digital
applications.

Description
The D371-Type Uncooled Laser Module consists of a
laser diode coupled to a single-mode fiber pigtail.
The device is available in a standard, 8-pin config-
uration (see Figure 1 and/or Table 1) and is ideal for
long-reach (SONET) and other high-speed digital
applications.
The laser diode is a narrow linewidth (<1 nm) DFB-
MQW single-mode laser and an InGaAs PIN photo-
diode back-facet monitor in an epoxy-free, hermeti-
cally sealed package.
